Polycarpaea rangaiahiana, a new species of Caryophyllaceae from the lateritic plains of Kannur District, Kerala, India is described and illustrated. P. rangaiahiana is morphologically similar to P. aurea from which differs in having ovate-lanceolate stipules with fimbriate margin and other floral characters. The name P. aurea is discussed from the nomenclatural point of view and a second-step typification was proposed.

A New Species

A new species, Stachys semsurensis (sect. Infrarosularis), is described and illustrated from Adıyaman province, Turkey. From the morphological point of view, it appears to be similar to Stachys cataonica, but it differs in several morphological features including densely covered with short stalked to subsessile glandular hairs in flowering stems, verticillasters congested into ± globose head, calyx teeth lanceolate-subulate, corolla white, tube exserted and nutlets obovoid, greyish-brown, reticulate. A comprehensive description of the new species is provided, including detailed photographs, geographical distribution map, habitat structure and ecology, vernacular name and IUCN conservation status.

Ophiorrhiza hiepii and O. hainanensis are reported as a new species and a new record for Vietnam respectively. O. hiepii is morphologically similar to O. subrubescens but differs by its smaller habit, usually unbranched stems, fewer secondary veins, umbelliform and sub-congested cymes, shorter corolla tubes and shorter stigma lobes in short-styled flowers. The mature flowers of O. hainanensis, which were unknown before, were measured in the wild for supplemental description of its floral characters. Additionally, the relationship between O. hainanensis and O. nutans, two easily confused species is clarified.

A New Species

Peliosanthes oksanae is described and illustrated as a new species from eastern Thailand. It is most similar to P. gracilipes known from northern and southwestern Thailand and northwestern Laos, from which it differs mainly by the shorter flowering stem, flowers borne singly or binately in the axils of the bracts and almost free oblong filaments not forming a typical corona. We briefly discuss taxonomic relationships between P. oksanae and two similar species, P. gracilipes and P. caesia. It is notable that especially P. oksanae and P. gracilipes are close in floral characters to Ophiopogon. We also report P. triandra, which was described from southern Cambodia, as new to Thailand. Both P. triandra and P. oksanae occurred in the same habitat.

The detailed study of several Cohniella specimens observed and/or collected in French Guiana shows that they all belong to a single entity and that it is different from the two species previously cited for this country, Cohniella cebolleta and C. ultrajectina, by a set of significant vegetative and floral characters. This entity is here described as a new species, illustrated and compared with the two taxa mentioned. A distribution map of the hitherto known specimens and/or populations is proposed, as well as an identification key.

A New Species

A new species of Cortinarius sect. Calochroi, C. lentus, is described on the basis of morphological and genetic features. It is characterised by a yellow-orange to brown-orange pileus, initially violaceous pink lamellae, a cream to pale yellow universal veil, amygdaliform to almost citriform spores, coarsely verrucose, typically narrow (Qav = 1.9) and habitat preference for chestnut woods on acidophilic soil. It is compared with the closest species from a morphological point of view, in particular with C. leochrous and C. calochrous. In order to assess its relative position within Calochroi, a phylogenetic approach based on RPB1 and ITS regions was performed. The ITS phylogenetic analysis did not resolve the position of C. lentus within sect Calochroi, but in our RPB1 phylogenetic analysis, C. sublilacinopes is closely related.

Silene crassiuscula,, a new species of S. sect. Dipterosperma, is described and illustrated from North-Western Sicily. It is an annual halophyte with succulent growing on carbonatic or calcarenitic rocks of coastal stands. From the morphological point of view , S. crassiuscula appears to be similar to the species belonging to the S. colorata group especially to S. nummica, from Sardinia, from which it differs in several features chiefly regarding the habit, leaves, inflorescences, floral pieces and seed micro-morphology. An analytical key of the taxa belonging to this section is also provided.

A New Species

The recent discovery of a new species of land iguana in the Galapagos (Tzika et al. 2008; Gentile et al. 2009; Gentile & Snell 2009) is indeed an exciting novelty, of great interest to all zoologists and evolutionary biologists. This species being apparently represented only by a very small population with a very limited range, it was described as a new taxon following an unusual procedure: no fixed specimen(s) (holotype or syntypes) was deposited in a permanent collection, but a live specimen, in which a transponder had been inserted and which then had been released, was designated as holotype. As analysed in detail by Dubois & Nemésio (2007), because of the unclear wording of Art. 16.4.2 of the Code, whether such a nomen is nomenclaturally available is open to question, and pending a clarification of the published Rules of the Code, will remain so. In this context, some comments on the paper by Gentile & Smell (2009), from a taxonomic and nomenclatural point of view, are in order. I thank Zhi-Qiang Zhang, Chief Editor of Zootaxa, for inviting me to contribute to this discussion.
